MARGlNAL AND SUB INDEX FOR TELEGRAPHIC ClPHER-CDES.

SPECIFICATION forming part of Letters Patent No.791,209, dated May 30, 1905.

Applicationiea october 1,1903. semina 175,387.

To all whom 'it may concern:

will enable others skilled in the art to which it appertains to make and use the same.

. This invention relates to improvements 'in marginal and sub index for telegraphic ciphercodes; and the objects of my improvement are,

first, to construct a book for a cipher-code having lateral marginal projectionsupon leaves thereof on which a marginal index is printed, written, stamped, cut, carved, in-

laid, engraved, or otherwise placed thereon,

consistingof a generic word or words; second, to pr1nt,wr1te, stamp, or otherwise place upon pages of a book containing a ci? pher-code a subindex comprising thegeneric word or words of the marginal index and thereunder on the same page print, write, stamp or otherwlse place thereon a specific word or words having a detailed and` related.Y

meaning to and under the generic wordV or wordsprinted or otherwise placed upon the projections of pages of thebook constituting the marginal index; third,'to select and to print or otherwise place upon, preferably at the top of a separate page or pages embraced within the body of the book, the one or more specific words, phrases, clauses, and sentences of the subindex and to print the reference to other pages of the book of the specific word orwords embraced within the body of the book for detailed information, and, fourth, to select and to print or otherwise place on pages included in the body portion of the book, preferably at the top of the pages, a surindex comprising a generlc word or words, desirably that on the marginal projection of the A y book, and thereunder a specific word or words contained in the subindex forming a part thereof and variety words under the speciiic words, and on the same line or lines with the variety word or words to select and to arrange a single corresponding arbitrary word for each `variety word or words designed to be transmitted electrically from one person or place to another.

The word surindex, hereinbefore mentior'ed and hereinafter employed in the specification and claims, denotes an'auxiliary index, a supplemental index, a part of the completed code.- It sustains the same relation to the subindex that the subindex bears to marginal index upon the projections forming pats of the leaves of the book containingthe co e.

I obtain these objectsby construction, se-

lection, and printed arrangement of words and characters, illustrated upon the accompanying drawings, in which- Figure 1 is a view in elevation showing the book open, illustrating one entire page thereof and the opposite page broken away longitudinally. Fig. 2 is a view in elevation of the upper portion of the book andthe lower portion thereof broken away. Fig. 3 is a like view to that illustrated upon Fig. 2 of lthe drawings, showing a part of a different page of the book.` Fig. 4c is a view in elevation of a portion of the upper part of aleaf of the book on which a part of the surindex may be printed, the central and lower portionof the leaf broken away. Fig. 5 is a view in elevation of portions of alea f of the book, showing parts of the surindex, the variety words, and corresponding arbitrary words printed thereon and the central and lower portion of the leaf broken away. Fig.l 6 isa view in elevation of portions of a leaf o f the book on which parts of the surindex, variety words, and corresponding arbitrary words are printed, the lower portion of the leaf broken away.

` Similar reference-numerals refer to like parts throughout the several views.

The reference-numerals 2,3, 4, 5, 6,7, '8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, and 21 refer to a group of two or more leaves of the book containing the code on which are formed lateral projections. On the projections of the first leaf of each of said group of leaves comprising the book I select and arrefer.

hensive meaning thereon constitute the marginal index. The subindexI preferably place upon the first page of each of the sa-id groups of leavesformingV the code hereinbefore referred to, and it (subindex) comprises a single word or words having comprehensive meaning-as, for example, the heading 30 upon figures of the drawings. I preferably select for such heading the word or words appearing upon the lateral marginal projection formed upon the same leaf of the book.

The generic word or words 30 having been chosen and preferably been placed at the upper left-handcorner of the same page of the book, said pages 10, 18, 26, 11, 21, and 29, shown, respectively, upon Figs. 1, 2, 3, 4, 5, and k6 of the drawings, as before referred to, I select and arrange and print thereunder a vertical column of words, phrases, clauses, or sentences 31,each'having a more definite meaning than the word or words chosen as aheading for a subindex. On the same line or lines, near the outer margin of the page on which the said column of wordsis placed having more definite meanings, I print or otherwise place thereon page reference-numerals 34. These are designed to indicate that on said pages to which the said numerals refer the surindex appears hereinafter more particularly described. Each surindex, as shown upon Figs. 4, 5, and 6 of the drawings, and referred to, respectively, by the referencenumerals 40, 4l, and 42, includes one of the sets of comprehensive generic wordor words 30, hereinbefore referred to, appearing upon one of the lateral marginal projections, as a heading for the surindex, and I preferably print the same at the top of each page of the book including the said index. To these pages of the surindex the page reference-numerals 34 (shown upon the Figs. l, 2, and 3 of the drawings) y In addition to the said comprehensive generic word. or words 30, chosen as a heading preferably placed at the top of each page embracing the surindex, thereunder I select and arrange and print or otherwise piace thereon two vertical columns of words 50 and 60. One column, 50, consists of words, phrases, clauses, and sentences denominated variety words. Theother column, 60, is made up of a series of single arbitrary words each arranged on a line with one of the words,phrases,clauses, or sentences in thefirst-mentioned column 50, hereinbefore referred to as variety words.

Whenever one of these variety words--the said phases, clauses, or sentences contained in column 50 first referred to-expresses the ideas one person desires to communicate electrically to another at a distance, the single corresponding arbitrary word in column on the same line as the variety word or variety words in the opposite column 50 is transmitted to the person desiring information. VEach person in communication being in possession of a cQpy of the book containing the code, the same definite information is conveyed by the single arbitrary word transmitted as would be conveyed by the corresponding variety word or words in the opposite column. By the transmission of these single arbitrary words the expense for telegraphing is greatly lessencd to the persons concerned.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings appended hereto.

It is obvious that many variations and changes in the details of construction, selection, and arrangement of my invention would readily suggest themselves to persons skilled in the art and still be within the spirit and scope of my invention.

I do not desire to confine this invention to the specific construction, selection, and arrangement of parts herein shown and described, and the right is reserved to make all changes in and modifications of the saine as come within the spirit of this invention, but I do desire to secure as my invention all features of construction and equivalents thereol', selections, and arrangements that come within the scope of my improvement as herein shown and described, and illustrated upon the drawings appended hereto.

Having described my invention, what I do claim, and desire to secure by Letters Patent, is-

1. In a telegraphic cipher-code, a marginal index comprising lateral projections formed upon the leaves of a book containine` the code, said projections having thereon a generic word or words appertaining to the trade to which the code relates, a subindex comprising the said generic word or words speciic word or words, Aand reference pagenumbers upon the same leaf of the book as that on which the said specific word or words are placed and a surindex including` therein arbitrary words.

2. A telegraphic cipher -code con'iprising lateral marginal projections formed upon the leaves of a book containing the code, said projections having thereon a generic werd or words relating to the particular trade in which the said code is intended to be used, a subindex consisting of the said generic word or words upon the said marginal projections, a specific Word or words, phrases,

clauses, sentences, and reference page-numbers, in combination with a surindex including therein a column of single arbitrary Words to be communicated from one person to another.

3. A telegraphic cipher-code comprising a marginal index having lateral marginal projections formed upon the leaves of a book,

said projections having thereon va generic Word or Words related to the subject-matter of the c ode, a subindeX comprising the said generic Word or Words, a specific Word or Words to the said generic Word or Words and reference page-numbers; and a surindexconsisting of variety Words and a single arb'itrary Word corresponding with each variety Word.

4. A telegraphic cipher-code comprising a marginall index having lateral projections formed'upon the leaves of a book, the said projections having thereon a gener1cWord or `Words, a subindeX upon the same page of the leaf of the book as that on Which the ge- EDMUN D PEYCKE.
